[0017] 1 shows a block diagram of a wireless communication system to which the embodiments of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be referred to as a terminal device or a user equipment (UE), and may be a terminal side device such as a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (Mobile Internet Device (MID)), a wearable device, a vehicle user equipment (VUE), a pedestrian user equipment (PUE), etc., and the wearable device may include a bracelet, an earphone, glasses, etc. It should be noted that the embodiments of the present application do not limit the specific type of the terminal 11.

It should be noted that the embodiments of this application only take base stations in an NR system as examples, and do not limit the specific type of base station.

[0018] In order to better understand the solutions of the embodiments of the present application, the following content will be introduced first.

[0019] Compared with traditional mobile communication systems, fifth-generation (5G) mobile communication systems must adapt to more diverse scenarios and business demands. Major 5G scenarios include enhanced mobile broadband (eMBB), ultra-reliable low latency communication (URLLC), and massive machine-type communication (mMTC). These scenarios require high reliability, low latency, wide bandwidth, and wide coverage. Some UEs may support different services. For example, a UE may support URLLC ultra-reliable and low latency services while simultaneously supporting eMBB services with high capacity and high data rates. In NR systems, different channels can have different starting symbols and lengths, resulting in overlapping transmission resources in the time domain. Generally, to maintain the uplink single-carrier characteristic, multiple overlapping PUCCHs transmitted in one slot can destroy the UE's single-carrier characteristic, and differences in transmit power can cause degradation of channel estimation performance. This situation is generally regarded as a kind of conflict, and a corresponding conflict resolution scheme needs to be designed to combine and discard some information.

[0020] Version 15 (Rel-15) PUCCH and PUCCH or PUCCH and PUSCH multiplexing Uplink control information (UCI) is transmitted on the PUCCH. Uplink data is transmitted on the PUSCH. There may be time overlap between different PUCCHs or between the PUCCH and the PUSCH due to factors such as the starting symbol and symbol length. In principle, the PUCCH and the PUSCH may be transmitted simultaneously, i.e., the UCI may be retained in the PUCCH. However, this increases the cubic metric and satisfies the out-of-band transmission requirement with higher transmit power. Furthermore, the relatively large frequency domain spacing (PUCCH is typically transmitted at both ends of the frequency band) when the PUSCH and the PUCCH are simultaneously transmitted poses challenges for radio frequency (RF) implementation. Therefore, in a normal case, UCI is multiplexed when the time domain resources of the PUCCHs that need to transmit UCI overlap, or when the PUCCH resources of the UCI that need to be transmitted and the PUSCH resources overlap in time, and the base station ensures that the UCI multiplexing processing time condition is met when scheduling this PUCCH / PUSCH, UCI is multiplexed into one PUCCH, or UCI and data are multiplexed into a PUSCH, and simultaneous transmission of different PUCCHs or simultaneous transmission of a PUCCH and a PUSCH is avoided. Specifically, see FIG. 2.

[0021] In the current protocol, a predefined timeline is defined for PUCCH-to-PUCCH or PUCCH-to-PUSCH multiplexing, i.e., a timeline that PUCCH-to-PUCCH multiplexing or UCI multiplexing must meet in PUSCH, and if the network-side scheduling does not meet this timeline, it is considered an error case.

[0022] Processing order for PUSCHs multiplexed between PUCCHs or multiplexed with UCI In one PUCCH group, there may be overlap between multiple PUCCHs, and one PUCCH may further overlap with multiple PUSCHs. In order to solve the time domain resource overlap problem between multiple uplink transmission channels, NR Rel-15 defines the processing order of UE uplink multiplexing, specifically as follows:

[0023] 1) In one time unit, when there are multiple PUCCHs and at least two PUCCHs overlap each other, the UE first resolves the overlap between the PUCCHs, and then obtains a maximum of two non-overlapping PUCCHs; 2) For a certain PUCCH output in 1), if this PUCCH does not overlap with a PUSCH, the UE transmits this PUCCH; if this PUCCH overlaps with a PUSCH, the UE multiplexes the UCI (excluding SR) carried by this PUCCH into a certain overlapping PUSCH according to a certain rule and transmits it.

[0024] Version 16 (Rel-16) Intra-UE Uplink Transmission Multiplexing and Priority To support different service demands, Rel-16 introduces different physical layer priorities and supports the following collision scenarios and defines the UE behavior for the following collision scenarios:

[0025] (1) High Priority (HP) uplink transmission vs. High Priority uplink transmission. The UE processes HP according to the Rel-15 scheme. (2) Low Priority (LP) uplink transmission vs. Low Priority uplink transmission. The UE processes according to the Rel-15 method. (3) High priority uplink transmission vs. low priority uplink transmission, the UE transmits the high priority uplink transmission and cancels the low priority uplink transmission.

[0026] Similarly, in order to give the UE sufficient capability to cancel the transmission of a low-priority PUCCH / PUSCH and transmit a high-priority PUCCH / PUSCH, the base station must meet certain timeline requirements when scheduling PUCCH / PUSCH, and current protocols also define timelines for PUCCH and PUCCH, or PUCCH and PUSCH prioritization.

[0027] Multicast broadcast service and its feedback Currently, NR technology has evolved through two versions, Rel-15 and Rel-16. These versions do not support broadcast / multicast features. However, there are many important usage scenarios, such as public safety and mission-critical applications, vehicle-to-vehicle and vehicle-to-infrastructure (V2X) applications, transparent Internet Protocol version 4 (IPv4) / Internet Protocol version 6 (IPv6) multicast delivery, interactive network television (IPTV), software delivery over wireless, and group communications and Internet of Things (IoT) applications. Therefore, in the next version, Rel-17, NR will introduce broadcast / multicast features. Broadcast / multicast services are primarily transmitted via the group-common PDSCH. The UE can receive the group-common PDSCH and the unicast PDSCH simultaneously.For the group-common PDSCH, the UE can feed back its HARQ-ACK information, which is similar to the HARQ-ACK information of the unicast PDSCH and can be divided into high-priority HARQ-ACK and low-priority HARQ-ACK. The low-priority HARQ-ACK and / or CSI / low-priority SR of the unicast PDSCH and the low-priority HARQ-ACK of the multicast PDSCH may be multiplexed together, or the high-priority HARQ-ACK and / or high-priority SR of the unicast PDSCH and the high-priority HARQ-ACK of the multicast PDSCH may be multiplexed together.

[0028] In NR, a processing order is defined when uplink transmission channels PUCCH / PUSCH transmissions of different types and different priorities collide, and multiplexing is also supported when HARQ-ACK and CSI / SR of unicast PDSCH and HARQ-ACK of multicast PDSCH overlap at the same time. However, when HARQ-ACK PUCCHs of different priorities, including multicast PDSCH, collide with other uplink transmission channels, it is necessary to solve how to determine the processing order of different channels / priorities.

[0029] The following describes in detail the method and apparatus according to the embodiments of the present application through specific examples and their application scenarios in conjunction with the drawings.

[0030] Referring to FIG. 3, an embodiment of the present application provides a method for processing time domain resource overlap of PUCCH, where the execution body of the method may be a terminal, and the specific steps include step 301.

[0031] Step 301: When there are a first HARQ-ACK and a second HARQ-ACK with the same priority, and the time domain resources of the PUCCH carrying the first HARQ-ACK and the PUCCH carrying the second HARQ-ACK overlap, or the PUCCH carrying the first HARQ-ACK and the PUCCH carrying the second HARQ-ACK are in the same time unit, and the terminal does not support transmitting PUCCHs of two HARQ-ACKs with the same priority in one time unit, the terminal multiplexes the first HARQ-ACK and the second HARQ-ACK into one PUCCH; The above-mentioned first HARQ-ACK and second HARQ-ACK having the same priority refers to the first HARQ-ACK and second HARQ-ACK having the same priority or the same corresponding priority index, for example, the first HARQ-ACK and second HARQ-ACK are both high priority and the corresponding priority index is 1, or the first HARQ-ACK and second HARQ-ACK are both low priority and the corresponding priority index is 0.

[0032] The first HARQ-ACK includes a group-common PDSCH HARQ-ACK and / or a group-common PDCCH HARQ-ACK. It can be understood that there may be a plurality of first HARQ-ACKs, and the plurality of first HARQ-ACKs may all be group-common PDSCH HARQ-ACKs, or the plurality of first HARQ-ACKs may all be group-common PDCCH HARQ-ACKs, or some of the plurality of first HARQ-ACKs may be group-common PDSCH HARQ-ACKs and some may be group-common PDCCH HARQ-ACKs. The embodiments of the present application are not specifically limited thereto. The second HARQ-ACK may be a unicast HARQ-ACK. The first HARQ-ACK may include a HARQ-ACK for a unicast PDSCH and / or a HARQ-ACK for a unicast PDCCH, and the priority of the first HARQ-ACK and the second HARQ-ACK may be the same. It can be understood that there may be multiple second HARQ-ACKs, and the multiple second HARQ-ACKs may all be HARQ-ACKs for unicast PDSCHs, or all be HARQ-ACKs for unicast PDCCHs, or some of the multiple second HARQ-ACKs may be HARQ-ACKs for unicast PDSCHs and other parts may be HARQ-ACKs for unicast PDCCHs, and the embodiments of the present application do not specifically limit this.

[0033] Specifically, the first HARQ-ACK is a HARQ-ACK for a group-common PDSCH and / or a HARQ-ACK for a group-common PDCCH that activates or releases a Semi-Persistent Scheduling (SPS) PDSCH, and the second HARQ-ACK is a HARQ-ACK for a unicast PDSCH and / or a HARQ-ACK for a unicast PDCCH that activates or releases an SPS PDSCH and / or a HARQ-ACK for a PDCCH that indicates dormancy of a secondary serving cell (Secondary Cell, Scell) and / or a HARQ-ACK for a PDCCH that triggers a type 3 codebook.

[0034] It should be noted that the group-common PDSCH or group-common PDCCH may also be called groupcast / multicast PDSCH or groupcast / multicast PDCCH, and mainly refers to a PDSCH or PDCCH that transmits to multiple recipients on the same physical resource.

[0035] In an embodiment of the present application, when the time domain resources of PUCCHs carrying a first HARQ-ACK and a second HARQ-ACK with the same priority overlap, or the PUCCHs carrying the first HARQ-ACK and the second HARQ-ACK are in the same time unit, and the terminal does not support transmitting PUCCHs of two HARQ-ACKs with the same priority in one time unit, the terminal multiplexes the first HARQ-ACK and the second HARQ-ACK into one PUCCH, thereby providing a method for handling overlapping time domain resources of an uplink channel PUCCH, which is applicable to a scenario of HARQ-ACKs including a group-common PDSCH and improves the efficiency of the communication system.

[0036] It should be noted that, for the sake of brevity, the first HARQ-ACK will be collectively referred to as M HARQ-ACK, the second HARQ-ACK will be collectively referred to as U HARQ-ACK, and correspondingly, the PUCCHs carrying the first HARQ-ACK will be collectively referred to as M HARQ-ACK PUCCHs, and the PUCCHs carrying the second HARQ-ACK will be collectively referred to as U HARQ-ACK PUCCHs. Furthermore, the first HARQ-ACKs with high priority are collectively referred to as M HP HARQ-ACKs and the corresponding PUCCHs are collectively referred to as M HP HARQ-ACK PUCCHs, the first HARQ-ACKs with low priority are collectively referred to as M LP HARQ-ACKs and the corresponding PUCCHs are collectively referred to as M LP HARQ-ACK PUCCHs, the second HARQ-ACKs with high priority are collectively referred to as U HP HARQ-ACKs and the corresponding PUCCHs are collectively referred to as U HP HARQ-ACK PUCCHs, and the second HARQ-ACKs with low priority are collectively referred to as U LP HARQ-ACKs and the corresponding PUCCHs are collectively referred to as U LP HARQ-ACK PUCCHs.

[0037] In one possible embodiment, the terminal multiplexes the first HARQ-ACK and the second HARQ-ACK into one PUCCH according to a preset rule; The preset rule includes one of the following:

[0038] (1) The terminal multiplexes the first HARQ-ACK and the second HARQ-ACK into a first PUCCH. When the time domain resources of the first PUCCH and the PUCCH carrying channel state information (CSI) and / or scheduling request (SR) overlap, the terminal multiplexes the first HARQ-ACK and the second HARQ-ACK, and the CSI and / or SR into a second PUCCH, where the CSI and / or SR have the same priority as the first HARQ-ACK and the second HARQ-ACK; In an embodiment of the present application, if a PUCCH carrying CSI and / or SR (hereinafter collectively referred to as a CSI PUCCH and / or SR PUCCH) may overlap with at least one of an M HARQ-ACK PUCCH and a U HARQ-ACK PUCCH, or if the CSI PUCCH and / or SR PUCCH does not overlap with at least one of an M HARQ-ACK PUCCH and a U HARQ-ACK PUCCH, the terminal may use the above multiplexing method for both of these two situations. That is, first, the M HARQ-ACK and the U HARQ-ACK are multiplexed into one PUCCH, for example, PUCCH1. As can be seen, since the priorities of the M HARQ-ACK and the U HARQ-ACK are the same, after multiplexing them into one PUCCH, the priorities remain the same. If this PUCCH1 overlaps with a CSI PUCCH and / or a SR PUCCH of the same priority, the terminal may further multiplex the HARQ-ACK (i.e., the M HARQ-ACK and the U HARQ-ACK) in PUCCH1. The CSI and / or SR (including HARQ-ACK) are multiplexed into one PUCCH, for example, PUCCH2.

[0039] It should be noted that the high priority and low priority SRs may be collectively referred to as HP SRs and LP SRs, respectively.

[0040] (2) When the time domain resources of the PUCCH carrying the CSI and / or SR and the PUCCH carrying the first HARQ-ACK overlap, and / or the time domain resources of the PUCCH carrying the CSI and / or SR and the PUCCH carrying the second HARQ-ACK overlap, the terminal multiplexes the first HARQ-ACK and the second HARQ-ACK, and the CSI and / or SR into a third PUCCH, and the CSI and / or SR have the same priority as the first HARQ-ACK and the second HARQ-ACK; In an embodiment of the present application, when the CSI PUCCH and / or SR PUCCH overlaps with at least one of the M HARQ-ACK PUCCH and the U HARQ-ACK PUCCH, the UE multiplexes the M HARQ-ACK, the U HARQ-ACK, and the CSI and / or SR into one PUCCH for transmission.

[0041] Specifically, in one possible embodiment, the terminal determines a third PUCCH from a PUCCH resource set corresponding to the first HARQ-ACK or a PUCCH resource set corresponding to the second HARQ-ACK according to a first number of bits, where the first number of bits is a sum of the number of bits of the first HARQ-ACK, the second HARQ-ACK, and the CSI and / or SR; In an embodiment of the present application, the terminal determines one PUCCH from the PUCCH resource set corresponding to M HARQ-ACK or the PUCCH resource set corresponding to U HARQ-ACK based on the number of multiplexed bits. For example, two PUCCH-configs are configured in the terminal, and PUCCH resource set (resource set 1) configured by one PUCCH-config is used to transmit U HARQ-ACK, and PUCCH resource set (PUCCH resource set 2) configured by the other PUCCH-config is used to transmit M HARQ-ACK. After the M HARQ-ACK and the U HARQ-ACK are multiplexed, one PUCCH resource is determined from PUCCH resource set 1 or PUCCH resource set 2 to transmit the multiplexed HARQ-ACK.

[0042] For one special scenario, when the first HARQ-ACK and the second HARQ-ACK are each 1 bit and the overlapping channel is only the SR PUCCH (no CSI PUCCH), the terminal determines the multiplexing mode of the first HARQ-ACK, the second HARQ-ACK, and the SR based on the format of the third PUCCH and the status of the SR.

[0043] For example, assume that M HARQ-ACK and U HARQ-ACK are each only 1 bit, and M HARQ-ACK and U HARQ-ACK are multiplexed onto U HARQ-ACK PUCCH or M HARQ-ACK PUCCH, and then multiplexed onto HARQ-ACK PUCCH, and M HARQ-ACK and U HARQ-ACK are transmitted on PUCCH as 2-bit HARQ-ACK.

[0044] Specifically, the above-mentioned determining the multiplexing manner of the first HARQ-ACK, the second HARQ-ACK and the SR based on the format of the third PUCCH and the state of SR includes:

[0045] (1) if the format of the third PUCCH is PUCCH format 0 and the status of the SR is positive, multiplex the SR into the HARQ-ACK PUCCH; (2) If the format of the third PUCCH is PUCCH format 1, the format of the SR PUCCH is PUCCH format 1, and the SR state is positive, multiplex the M HARQ-ACK and U HARQ-ACK into the SR PUCCH. If the format of the third PUCCH is PUCCH format 1, the format of the SR PUCCH is PUCCH format 1, and the SR state is negative, transmit this third PUCCH.

[0046] (3) If the time domain resources of the PUCCH carrying CSI and / or SR overlap with the PUCCH carrying the first HARQ-ACK and / or the time domain resources of the PUCCH carrying CSI and / or SR overlap with the PUCCH carrying the second HARQ-ACK, the terminal multiplexes the second HARQ-ACK and CSI and / or SR onto a fourth PUCCH; if the time domain resources of the fourth PUCCH and the PUCCH carrying the first HARQ-ACK overlap with each other, the terminal multiplexes the first HARQ-ACK and the second HARQ-ACK, and CSI and / or SR onto a fifth PUCCH, and the CSI and / or SR have the same priority as the first HARQ-ACK and the second HARQ-ACK.

[0047] In an embodiment of the present application, in the case where the CSI PUCCH and / or SR PUCCH overlaps with at least one of the M HARQ-ACK PUCCH and the U HARQ-ACK PUCCH, the terminal first multiplexes the U HARQ-ACK with the CSI and / or SR. If the multiplexed PUCCH overlaps with the M HARQ-ACK PUCCH or they do not overlap but the terminal does not support transmitting two HARQ-ACK PUCCHs of the same priority in one time unit, the terminal multiplexes this multiplexed PUCCH with the M HARQ-ACK PUCCH, i.e., multiplexes the M HARQ-ACK, U HARQ-ACK, and CSI and / or SR into one PUCCH. Alternatively, if the terminal supports transmitting two HARQ-ACK PUCCHs of the same priority in one time unit, the terminal transmits the M HARQ-ACK PUCCH and the PUCCH multiplexed with the U HARQ-ACK, CSI, and SR, respectively.

[0048] It should be noted that if both terminals support transmitting two HARQ-ACK PUCCHs of the same priority in one time unit, both terminals may also support transmitting U HARQ-ACK PUCCHs and M HARQ-ACK PUCCHs of the same priority in one time unit.

[0049] In one possible embodiment, by default, the terminal may not support transmission of two HARQ-ACK PUCCHs of the same priority in one time unit (e.g., one HARQ-ACK PUCCH corresponds to a unicast PDSCH / PDCCH and one HARQ-ACK PUCCH corresponds to a group-common PDSCH / PDCCH), i.e., a PUCCH multiplexed with U HARQ-ACK and CSI and / or SR may be directly multiplexed with M HARQ-ACK PUCCH, regardless of whether the time domain resources overlap.

[0050] In some embodiments, there are a first HARQ-ACK and a second HARQ-ACK with the same priority, and a first HARQ-ACK and a second HARQ-ACK with different priorities, and there is a case where the time domain resources of the PUCCH carrying the first HARQ-ACK and the PUCCH carrying the second HARQ-ACK with different priorities overlap; Specifically, the above-mentioned existence of a first HARQ-ACK and a second HARQ-ACK with the same priority and a first HARQ-ACK and a second HARQ-ACK with different priorities includes any one of the following:

[0051] (1) The terminal configures or schedules a PUCCH carrying a first HARQ-ACK of a first priority, a PUCCH carrying a first HARQ-ACK of a second priority, and a PUCCH carrying a second HARQ-ACK of a first priority; That is, the terminal configures or schedules an M LP HARQ-ACK PUCCH, an M HP HARQ-ACK PUCCH, and a U LP HARQ-ACK PUCCH.

[0052] (2) The terminal configures or schedules a PUCCH carrying a first HARQ-ACK of a first priority, a PUCCH carrying a first HARQ-ACK of a second priority, and a PUCCH carrying a second HARQ-ACK of a second priority; That is, the terminal configures or schedules the M LP HARQ-ACK PUCCH, the M HP HARQ-ACK PUCCH, and the U HP HARQ-ACK PUCCH.

[0053] (3) The terminal configures or schedules a PUCCH carrying a first HARQ-ACK of a first priority, a PUCCH carrying a second HARQ-ACK of a first priority, and a PUCCH carrying a second HARQ-ACK of a second priority; That is, the terminal configures or schedules the M LP HARQ-ACK PUCCH, the U LP HARQ-ACK PUCCH, and the U HP HARQ-ACK PUCCH.

[0054] (4) The terminal configures or schedules a PUCCH carrying a first HARQ-ACK of a second priority, a PUCCH carrying a second HARQ-ACK of the first priority, and a PUCCH carrying a second HARQ-ACK of the second priority; That is, the terminal configures or schedules the M HP HARQ-ACK PUCCH, the U LP HARQ-ACK PUCCH, and the U HP HARQ-ACK PUCCH.

[0055] (5) The terminal configures or schedules a PUCCH carrying a first HARQ-ACK of a first priority, a PUCCH carrying a first HARQ-ACK of a second priority, a PUCCH carrying a second HARQ-ACK of a first priority, and a PUCCH carrying a second HARQ-ACK of a second priority.

[0056] That is, the terminal configures or schedules the M LP HARQ-ACK PUCCH, the M HP HARQ-ACK PUCCH, the U LP HARQ-ACK PUCCH, and the U HP HARQ-ACK PUCCH.

[0057] Specifically, for the case where there are a first HARQ-ACK and a second HARQ-ACK with the same priority and a first HARQ-ACK and a second HARQ-ACK with different priorities, and the time domain resources of the PUCCH carrying the first HARQ-ACK and the PUCCH carrying the second HARQ-ACK with different priorities overlap, the method includes the following processing manner, where the second priority is higher than the first priority:

[0058] Method 1: (1) The terminal cancels transmission of a PUCCH carrying a first HARQ-ACK of a first priority and / or a PUCCH carrying a second HARQ-ACK of a first priority; (2) The terminal multiplexes the first HARQ-ACK of the second priority and the second HARQ-ACK of the second priority into a sixth PUCCH based on a preset rule; In an embodiment of the present application, the terminal first discards or cancels the transmission of the low-priority HARQ-ACK PUCCH, and then multiplexes the high-priority HARQ-ACK into one PUCCH for transmission.

[0059] Method 2: The terminal multiplexes the first HARQ-ACK of the first priority and the second HARQ-ACK of the first priority into a seventh PUCCH based on a preset rule; If the time domain resources of the seventh PUCCH and the PUCCH carrying the first HARQ-ACK of the second priority overlap, and / or the time domain resources of the seventh PUCCH and the PUCCH carrying the second HARQ-ACK of the second priority overlap, the terminal cancels the transmission of the seventh PUCCH; The terminal multiplexes the first HARQ-ACK of the second priority and the second HARQ-ACK of the second priority into an eighth PUCCH according to a preset rule; In an embodiment of the present application, the terminal first multiplexes low-priority HARQ-ACKs into one PUCCH according to the preset rule for multiplexing HARQ-ACKs of the same priority, then handles overlapping between the multiplexed PUCCHs and high-priority HARQ-ACK PUCCHs, i.e., discards or cancels the transmission of the low-priority HARQ-ACK PUCCH, and finally multiplexes high-priority HARQ-ACKs into one PUCCH according to the preset rule. If there is a low-priority PUCCH that overlaps with the resource after the high-priority HARQ-ACK PUCCH, the overlapping low-priority PUCCH is discarded or canceled.

[0060] Method 3: The terminal multiplexes the first HARQ-ACK of the first priority and the second HARQ-ACK of the first priority into the ninth PUCCH based on a preset rule; The terminal multiplexes the first HARQ-ACK of the second priority and the second HARQ-ACK of the second priority into a tenth PUCCH according to a preset rule; If the time domain resources of the ninth PUCCH and the tenth PUCCH overlap, the terminal cancels the transmission of the ninth PUCCH; In an embodiment of the present application, the terminal first multiplexes the high-priority HARQ-ACK and the low-priority HARQ-ACK according to the preset rule, and then performs overlap processing on the two multiplexed PUCCHs, i.e., discards or cancels the transmission of the low-priority HARQ-ACK PUCCH.

[0061] The method for handling PUCCH time domain resource overlap in the present application will be described below in conjunction with a specific embodiment.

[0062] Example 1: When resources of a low-priority HARQ-ACK PUCCH (U LP HARQ-ACK PUCCH) of a unicast PDSCH and a low-priority HARQ-ACK PUCCH (M LP HARQ-ACK PUCCH) of a group common PDSCH collide, the UE multiplexes the U LP HARQ-ACK and the M LP HARQ-ACK into one PUCCH for transmission. However, if the overlapping channels further include a CSI PUCCH and / or an LP SR PUCCH, the UE must further multiplex the CSI and / or the LP SR together. Here, the UE may process the overlapping PUCCH channels in the following manner.

[0063] Method 1: Referring to Figure 4a, it is assumed that the UE first multiplexes the U LP HARQ-ACK and the M LP HARQ-ACK into one channel and then multiplexes them onto PUCCH1. If PUCCH1 overlaps with CSI and / or LP SR, the UE multiplexes the U LP HARQ-ACK and the M LP HARQ-ACK into one channel with CSI and / or LP SR.

[0064] Method 2: Referring to FIG. 4b, the UE multiplexes U LP HARQ-ACK, M LP HARQ-ACK, CSI and / or LP SR into one PUCCH channel.

[0065] Method 3: Referring to FIG. 4c, the UE first processes the overlap between the U LP HARQ-ACK and the CSI / LP SR PUCCH. For example, the UE multiplexes the U LP HARQ-ACK and the CSI / LP SR into one PUCCH. This channel is the U LP HARQ-ACK PUCCH (e.g., when the U LP HARQ-ACK PUCCH is PUCCH format 0 and the U LP HARQ-ACK PUCCH and the LP SR are multiplexed), or the LP SR PUCCH (e.g., when the U LP HARQ-ACK PUCCH is PUCCH format 1 and the U LP HARQ-ACK PUCCH and the LP SR PUCCH are PUCCH format 1 and are multiplexed), or the CSI PUCCH (e.g., when the U LP HARQ-ACK is a HARQ-ACK fed back from the SPS PDSCH, i.e., when there is no PDCCH corresponding to the U LP HARQ-ACK PUCCH and the U LP SR PUCCH is multiplexed). The PUCCH may be determined based on the number of bits of multiplexed UCI (e.g., when there is a PDCCH corresponding to the U LP HARQ-ACK PUCCH or when the CSI PUCCH is a multi-CSI PUCCH). Assuming that a UE multiplexes U LP HARQ-ACK and CSI and / or LP SR onto PUCCH1, if PUCCH1 overlaps with M LP HARQ-ACK PUCCH, the UE further multiplexes the UCI carried by PUCCH1 with the M LP HARQ-ACK. If PUCCH1 does not overlap with the M LP HARQ-ACK PUCCH and the UE supports transmitting PUCCHs carrying two HARQ-ACKs of the same priority in one time unit (e.g., slot), the UE transmits PUCCH1 and the M LP HARQ-ACK PUCCH respectively. If the UE does not support transmitting PUCCHs carrying two HARQ-ACKs of the same priority in one time unit, the UE multiplexes the UCI carried by the M LP HARQ-ACK PUCCH and PUCCH1 into one PUCCH, or the UE transmits one of PUCCH1 and the M LP HARQ-ACK PUCCH and discards the other.

[0066] For example, the U LP HARQ-ACK PUCCH is in PUCCH format 0 / 1, the M LP HARQ-ACK PUCCH is in PUCCH format 0 / 1, and multiple LP SRs are in PUCCH format 0 / 1.

[0067] When the UE first multiplexes the U LP HARQ-ACK and the M LP HARQ-ACK, it should determine one PUCCH, for example, PUCCH1, based on the number of bits of the multiplexed HARQ-ACK. If the multiplexed PUCCH still overlaps with the LP SR resource, it multiplexes the LP SR with the HARQ-ACK (this can be done according to the conventional multiplexing method, for example, if PUCCH1 is PUCCH format 2 / 3 / 4, K bits of SR information are multiplexed with the HARQ-ACK, where K=log2(1+m), and m is the number of SR configurations that overlap with the PUCCH1 resource).

[0068] When the UE first processes the overlap between U LP HARQ-ACK and LP SR, the UE multiplexes only 1-bit SR information with U LP HARQ-ACK. If it then multiplexes with M LP HARQ-ACK, there is still only 1-bit SR information in the PUCCH if the multiplexed channel is PUCCH format 2 / 3 / 4.

[0069] For overlapping between high priority PUCCHs, the above three methods are also applied, specifically see Figures 4d to 4f.

[0070] Example 2: In this embodiment, the time domain resources of the M LP HARQ-ACK PUCCH and the U LP HARQ-ACK PUCCH do not overlap in one time unit, but the UE can only transmit one LP HARQ-ACK PUCCH in one time unit. In this case, the time domain resources of the U LP HARQ-ACK and / or M LP HARQ-ACK PUCCH also overlap with the time domain resources of the CSI PUCCH and / or the LP SR. In this case, the UE may proceed in the following manner:

[0071] Method 1: Assume that the UE first multiplexes the M LP HARQ-ACK and U LP HARQ-ACK into one PUCCH and then multiplexes them onto PUCCH1. If the time domain resources of this PUCCH1 and the CSI and / or LP SR overlap, the UE further handles collisions between the CSI and / or LP SR. If there is no overlap, the UE transmits the HARQ-ACK PUCCH and the CSI and / or LP SR PUCCH, respectively.

[0072] Method 2: Assume that the UE first processes directly overlapping channels (i.e., channels with overlapping transmission resources). As shown in Figure 4g, the UE first multiplexes the U LP HARQ-ACK, CSI, and LP SR onto PUCCH1. Then, it multiplexes the M LP HARQ-ACK onto PUCCH1 (whether they overlap or not). As shown in Figure 4h, the UE first multiplexes the M LP HARQ-ACK and CSI, and the U LP HARQ-ACK and LP SR. Then, it further multiplexes the multiplexed channels together (whether they overlap or not).

[0073] Example 3: If the M HARQ-ACK PUCCHs of different priorities overlap with the U HARQ-ACK PUCCHs, and the M HP HARQ-ACK PUCCHs overlap with the U HP HARQ-ACK PUCCHs, the UE may proceed as follows:

[0074] Method 1: The UE first discards or cancels the U LP HARQ-ACK PUCCH, and then multiplexes the U HP HARQ-ACK and M HP HARQ-ACK into one channel for transmission; Method 2: Assume that the UE first multiplexes the U HP HARQ-ACK and M HP HARQ-ACK onto one channel for transmission and then multiplexes them onto PUCCH1. If PUCCH1 overlaps with the U LP HARQ-ACK PUCCH, the UE discards or cancels the U LP HARQ-ACK PUCCH transmission. If PUCCH1 does not overlap with the U LP HARQ-ACK PUCCH, the UE transmits the U LP HARQ-ACK PUCCH and PUCCH1 separately.

[0075] Example 4: In a certain time unit, the UE configures or schedules M HP HARQ-ACK PUCCH, M LP HARQ-ACK PUCCH, U HP HARQ-ACK PUCCH, U LP HARQ-ACK PUCCH with different priorities, as well as CSI, HP SR, and LP SR. If the above channels overlap on the time domain resource, the UE may proceed in the following manner:

[0076] It should be noted that in the embodiments of the present application, the CSI is described as a low-priority CSI as an example, and the above method is similarly applied to a high-priority CSI.

[0077] Method 1: The UE first processes overlap between LP channels (which may further include non-overlapping scenarios in the case of M LP HARQ-ACK and U LP HARQ-ACK) according to the method in the above embodiment 1 / 2, then processes overlap between high priority channels and low priority channels (e.g., discards or cancels low priority channel transmission), then processes overlap between HP channels (which may further include non-overlapping scenarios in the case of M HP HARQ-ACK and U HP HARQ-ACK) according to the method in the above embodiment 1 / 2, and finally processes overlap between high priority channels and low priority channels (e.g., discards or cancels low priority channel transmission). Method 2: The UE first processes overlap between LP channels and overlap between HP channels according to the methods in the above embodiments 1 / 2 (in the case of M LP HARQ-ACK and U LP HARQ-ACK, it may further include non-overlapping scenarios, and in the case of M HP HARQ-ACK and U HP HARQ-ACK, it may further include non-overlapping scenarios), then processes overlap between high priority channels and low priority channels (e.g., discards or cancels low priority channel transmission), and then processes overlap between high priority channels and low priority channels (e.g., discards or cancels low priority channel transmission).
